NSW can experience heavy rains and significant flooding, resulting in water lying around. Stagnant water provides ideal conditions for mosquito breeding.

With more mosquito breeding there is an increased risk of exposure to mosquito-borne viruses such as Ross River virus (RRV) or Barmah Forest virus (BFV), Japanese encephalitis virus (JEV), Murray Valley encephalitis virus (MVE), or Kunjin virus.

The following measures can be considered depending on the abundance of mosquitoes or nuisance biting, local detection of mosquito-borne diseases, the environmental impact of insecticide use, and local environmental condition. To reduce the number of mosquitoes surrounding your property or in public areas, consider the following steps:

Events held in warmer months with substantial outdoor components should consider implementing measures to reduce the risk of mosquito-borne disease.

The following measures can be considered depending on the risk associated with the event. For advice on determining the level of risk, event organisers can contact their local public health unit on 1300 066 055.

Expert advice should be sought when selecting an appropriate chemical product for local conditions as the timing of the application of these products is critical to achieving successful mosquito control.
